Mix the cumin, lime zest, garlic powder, cilantro, chili powder, jalapeno, lime juice, oil, and Roasted Beef Base into a bowl; whisk to combine. Remove a ¼-cup of the marinade and reserve. Add the steak to the bowl and marinate the meat for 15 minutes.

Place the skewers directly onto the grill, baste with the reserved marinade and grill for 2 minutes per side.

Serve with your favorite fajita sides.

Try with mushrooms, zucchini and squash or any other favorite vegetable. Also, try this dish with Better Than Bouillon® Organic Roasted Beef Base.
If you have time, allow your meat to marinate in the refrigerator for 2 or more hours before grilling.
